OHU RNs SPECIFICATION forming part of Letters Patent No. 629,238, datedJuly 18, 1899.

I Application filed April 22, 1899. Serial No. 714,144. (No model.)

' citizen of the United States, residing at Corrigan, in the county ofPolk and State of Texas, have invented certain new and usefulImprovements in Ohurns, of which the following is a specification.

My invention is a churn-motor or means for operating the churn-dasher.

By this invention the dasher is moved in two directions at the sametime. It has a vertical motion and a spiral motion both at the sametime, because of the fact that the dasher-rod has two spiral groovesrunning from one end to the other, giving the dasherrod one turn as itgoes up and one turn as it comes down 3 but by releasing the guides thatwork in the grooves it has but one motiona vertical motion. I

While this device is primarily intended to operate a churn-dasher, itmay also operate a post-hole digger.

In the accompanying drawings, Figure 1 is a perspective view of myinvention. Figs. 2, 3, 4, and 5 are detail views. Fig. 6 is a top planview of the dasher. Fig.7 is a perspective view of a post-hole digger.

My invention is described as follows:

1 is a beam. 2 are legs inserted in the same. 3 is a verticallongitudinal slot in said beam and in which is journaled asprocket-wheel 4.

5 are rods set vertically in the forward end of the beam 1, enlarging attheir upper ends into head-pieces 6. These head-pieces are secured inproper position by a cross-piece. These rods 5 are held in theirvertical positions by braces 7, their upper ends secured to the heads 6and their lower ends to the beam 1. Between the heads 6 is journaled asprocket-pulley 8. This pulley is journaled on the crank-shaft 9, and inthe U-bend 10 of this crank-shaft is pivoted the upper end of pitman-rod11, the lower end of which is pivoted in a bearing 12 of a doublesleeveblock 13, through the perforations 14 of which are run thestandards 5. This sleeve-block 13 has a forward projection 15, in'whichis firmly secured the churn dasher-rod 16, which passes down through aperforation 17 in the beam 1. This dasher-rod 16 is provided with twospiral slots 18. (See Fig. 4.) --This view, Fig. 4, is a cross-sectionalview of said dasherbest and most approved styles.

rod. The forward end of beam 1 is cut away on either side, forming tworecesses 19, and leading from the outer faces of these recesses inwardlyto perforations 17 are two horizontal perforations 20. Theseperforations are coneshaped, their smaller ends terminating inthevertical perforation 17. Fitting in these recesses 19 are hinged twoarms 21,.each arm provided with a projection 22, cone-shaped and adaptedto fit in the perforations 20, their points reaching to and fitting inthe spiral grooves 18 of the dasher-rod 16, so that when the dasherrodmoves up it is made, by reason of the grooves 18 and projections 20, tomake'one revolution and when it moves down to make one revolution. Thesehinged arms are held in place by a bolt and nut 23 and the other endwhen closed by bolt and nut 24.

. When I want to run the rod 16 up and down without having it revolve, Itake away the The operation of this motor is too apparent to needexplanation. The lower end ofthe dasher-rod 16 is provided with any kindand any number of dasher-wings, and under the beam 1 and so situatedthat the rod 16 may play. up and down therein is set the churnpail,which may be made after any of the When this device is used as apost-hole digger, any spade that is adaptedto digging post-holes may besecured to the lower end of the rod 16.
